COTTON-GIN.

SEEGFIGATON forming' part of Letters Patent No. 668,470, dated February19, 1901.

Application tiled April 18, 1900. Serial No. 13,325. (No modela .To allwhom t ntctg/ concern.-

Be it known that I, WILLIAM HENRY WENT- WORTH, a citizen of the UnitedStates, and a residentof San Antonio,in the county of Bexar and State ofTexas, have invented a new and Improved Cotton-Giu, of which thefollowing is a full, clear, and exact description.

One purpose of the invention is to so construct a cotton-gin that therollers, feed devices, and blades will be vertically disposed andarranged in groups, which arrangement by the multiplication of groupsadmits of a single gin-stand being economically erected which will equalthe capacity of a battery of gins now in general use.

Another purpose of'the invention is to simplify the construction ofcotton-gine and provide a speedy and effective separation of the seedfrom the fiber without injury to the latter and a thorough separation ofthe treated fiber from the seed.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the 'Iigures Figure 1 is a perspective viewof the improved gin. Fig. 2 is a horizontal section taken practically onthe line 2 2 of Fig. 3. Fig. 3 is a vertical section taken substantiallyon the line 3 3 of Fig. 4, and Fig. 4 is a `horizontal section takenpractically on the line 4 4 of Fig. 3. A

The gin is preferably of cylindrical shape, and the body comprises acircular base A, a circular head B, and a cylindrical body C, of lessdiameter than the head and the base. The body C is substantiallyindependent of the base; but the head B is attached to the base Athrough the medium of suitable rods 11 or their equivalents. The base Ais provided with legs 10, whereby the gin may be secured to the floor orother support.

The body C is provided with a bottom 12, in which a circular opening 13is made, as shown in Figs. 3 and 4, and a corresponding opening 14 ismade in the base A, as illustratcd in Figs. 2 and 3. Toothedguide-rollers 15 are mounted in the upper surface of the base, betweenthe periphery thereof and the central opening 14, and a master-wheel Dis mounted to travel on these toothed guiderollers 15, the master-wheelhaving teeth 1G upon its under surface, and the said masterwlieel isfurther provided with teeth 17, formed in its inner edge, and teeth 18,produced upon its outer edge, as is best shown in Fig. 2.

In order that the master-wheel may revolve and not be subjected to unduefriction by reason of the weightof the body O, plain friction-rollers 19are fitted in the bottom portion of said body, as illustrated in Fig. 3,which plain friction-rollers engage with the upper surface of themaster-wheel D, which surface is plain. The master-wheel is turned byengagement with a gear 20, the `gear meshing with the bottom teeth ofthe master-wheel, and this gear is mounted on a shaft 21, provided witha suitable pulley 22, adapted for connection with any source of power.

The body C is divided into a series of compartments E and chambers F,alternately arranged, the compartments being separated from the chambersby vertical partitions 23, which extend from the outer surface of thebody to the edge of the opening 13 in the bottom of the body, and anopposing vertical partition 24, which extends from the outer surface ofthe body to a point about midway between the said surface and the edgeof the said opening 13. The partitions 23 and 24 are curved or bowedoutward or in opposite directions except at their outer edges, whichportions 25 ot' the said partitions are straight. The space thus formedin each compartment E is adapted to receive a feed board or plate 26.These feed boards or plates are attached by means of pivots 27 to theunder surface of the head B, as shown in Fig. 3, while arms 28 varepivctally attached to the outer faces of the said feed boards or platesnear their lower ends, which arms extend out through suitable openingsin the body-casing and are pivot-ally connected with crank arms 29,

formed in shafts 30, journaled at their upper4 ends in suitable brackets31, carried by the body-casing, and the lower ends of the shafts 30 aresuitablyjournaled in the base A. Each shaft 30 has a pinion 32 securedthereto, and these pinions mesh with the exterior teeth on themaster-wheel D. Therefore as the masterwheel revolves the feed plates orboards 26 are laterally reciprocated,swinging upon their pivots. Inorder that cotton shall not stick in the bottom portion of the sectionof the compartment E in which the feed-board is located, the bottom c ofthis portion of each compartment E is inclined from the body-easingdownward and inward, as shown in Fig. 3. A vertical roller 33 is mountedto turn in the wider portion of each compartment E, which compartmentsare adapted to receive the seed-cotton, and these rollers are journaledin any suitable manner in the head and in the base of the gin, thetrnnnions or shafts of the rollers passing loosely through the floor 12of the body C. Each roller 33 is preferably provided with a covering 34of hide, having the hair on the outside and cut off short, or therollers may be covered with any other material adapted to attract andtake hold of the seed-cotton. As the rollers revolve they carry theseed-cotton to two blades 36 and 37, located at the spaces in thecompartments Eformed by the shorter partitions 24, as is illustrated inFig. 4. The blade 36 is a stationary blade and is attached to an uprightsupport 35, which extends from the bottom of the body C to the head B,quite close to the edge of the central opening 13 in the said bottom,and these blades 36 are adapted to engage with the peripheral surfacesof the rollers 33, as is also shown in Fig. 4. The blades 37 are movableto and from the stationary blades 36, being guided in ways produced inblocks 38, located upon the inner face of the head B and the bottom l2of the body C. Each movable blade 37is preferably provided with two arms39, and these arms extend through suitable openings in the body-casingand are pivotally connected with crank-arms 41, formed in shafts 40,said shafts being journaled in the head B and the base A. Each shaft 40at its lower end has an attached pinion 42, which meshes with theexteriorI teeth of the master-wheel D. Thus as the master-wheel isrevolved the blades 37 are moved to and from the Xed blades 36.

The seed-cotton is fed into the compartments E through openings 43 madein the head B, and as the seed-cotton is thus fed to the compartments Eit falls between the feed boards or'plates 26 and the rollers 33. Afterit has been separated from the seed by the action of the blades 36 and37 the fiber is delivered to the central openings or wells 13 and 14,while the seeds fall to the ground through openings 44, made in thebottom 12 of the body, and corresponding openings 45, produced in thebaseA; but it will be understood that the cotton may be conducted to anydesired point by suitable conveyers passing beneath the wells 14, andconveyers likewise may be provided to receive the cotton-seed. Each ofthe rollers 33 is provided below the bottom of the body C with anattached gear 46, as shown in Figs. 2 and 3, and these gears mesh withthe inner teeth 17 of the master-wheel D, and by this means the rollersare made to revolve simultaneously with the movement of the 1 movableblades 37 and the feed boards or plates 26.

In operation the seed-cotton is forced by the feed-boards to the rollersand the rollers conduct the seed-cotton to the space between the fixedand movable blades, and by reason of'the action of the movable blades inconnection with the fixed blades the cotton-seeds are forced from thefiber and by reason of their weight drop down to the exit-openings 44,while the iiber passes beneath the stationary blade to the opening 14.(See Fig. 2.) The chambers F are very useful, as they enable the bladesto be adjusted or any cotton that may clog to be started on its way, andto that end each chamber F is provided with a door f, made in thebody-casing.

When a gin is constructed as above set forth, the risk of fire isgreatly lessened and the mutilation of the operator is made almostimpossible. The gin can be used for cleaning or burring wool or mohairand all raw material of such class, it being understood that when themachine is so used the rollers are changed, as the grease, dto., fromthe wool would injure the cotton ber. By subjecting the fiber to theaction of the stationary blades while the Iiber is gripped by therollers the ber is not only separated from the seed, but compressed,leaving the fibers parallel.

Having thus described my invention, I claimas new and desire to secureby Letters Patent- 1.
